This regulatory evaluation accompanies the agency's proposal to upgrade FMVSS 213. The Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act, Public Law 106-414, asks the agency to conduct a detailed review of FVMSS 213, "Child Restraint Systems" and determine whether the standard should be revised as outlined in the Act. In response to the TREAD Act, the agency has conducted a number of research projects to improve FMVSS 213.

    Based on the research project results and following the TREAD Act provisions, the agency is proposing, among other things, that FMVSS 213 should be incorporating (1) a 12-month-old CRABI (1), a Hybrid III 3-year-old, and a Hybrid III 6-year old in the standard's compliance test; (2) FMVSS 208 scaled child injury criteria, with a modification in the neck injury criteria; (3) an upper weight limit of 65 pounds extended from 50 pounds by using Hybrid III weighted 6-year old dummy; (4) a representative of production child safety seat assembly and crash pulse; and (5) short-term approaches to improve child occupant safety in child restraints in side impact crashes.

    This regulatory evaluation analyzes the potential impact of the agency's proposal to use new dummies (CRABI, the Hybrid III 3-, 6-, and weighted 6-year-old dummies), to incorporate FMVSS 208 injury criteria and its scaled injury criterion performance limits (ICPLs), and to use the new seat assembly and sled crash pulse.

    1 Originally this dummy was named the Crash Research Air Bag Interaction Dummy.
